Mechanical properties of miscanthus (m. giganteus) as related to fall harvest
Authors: Zhang, S, J Liu
Description: Switchgrass and miscanthus are dedicated energy crops. These high yield perennial crops can be planted in marginal lands and harvested once a year. To investigate the efficiency and energy consumption of existing harvest machines and develop new processing equipment, mechanical properties of these energy crops are needed. Dynamic properties including shearing, bending, and compression of plant stems were tested in laboratory using a specially-designed test device. Impact of loading speed and type of cutting knifes on test results were considered in this research. Results can be used to simulate or estimate energy/power needed for mowing and baling processes.
